The Endpoint Hardening solution includes the secure configuration of workstations, servers, cameras, NVRs, VMS servers, and other network-connected devices, reducing the attack surface and strengthening the overall security posture.

The architecture is structured to standardize security baselines, restrict unnecessary services, apply access policies, and ensure that devices operate with configurations aligned to the criticality of the environment.

A3A Engenharia de Sistemas develops each solution based on asset inventory, exposure analysis, vulnerability mapping, and definition of secure configuration standards, ensuring traceability and continuity of protection.

SCOPE OF WORK

Within the scope of Endpoint Hardening, A3A Engenharia de Sistemas can operate in the following areas:
